Double Pitch roller chains are generated in accordance with all the ASME/ANSI B29.3 (Transmission Series) and B29.four (Conveyor Series) American roller chain standards. Usually these chains are similar to ASME/ANSI regular products except that the pitch is double. These are out there in Transmission Series, Conveyor Series with Standard (small) Rollers and Conveyor Series with Big (oversized) Rollers.
Transmission Series
This series is usually applied on drives with slow to moderate speeds, reduced chain loads and prolonged center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain quantity is obtained by including 2000 towards the ASME/ANSI chain variety as well as prefi x letter ?¡ãA?¡À. Note that some providers never use a prefi x letter for this series so the chains may perhaps be represented as A2040, A2050 and so on. or 2040, 2050 and so forth.
Conveyor Series with Conventional (little) Rollers
This series is usually applied on light to moderate load materials managing conveyors with or devoid of attachment links. The side plate contour is straight for enhanced sliding properties. Pitch sizes of 1-1/2?¡À and bigger have ?¡ãHeavy?¡À series link plates (i.e. website link plates with the next more substantial chain dimension. The chain number is discovered by incorporating 2000 to your ASME/ANSI chain amount plus the prefi x letter ?¡ãC?¡À. Chains with the ?¡ãheavy?¡À sort side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Massive (oversized) Rollers
These chains possess large rollers in order that the chain rolls on a conveyor track lowering friction. Chain numbers are uncovered within the similar way as mentioned over except that the last digit about the chain number is altered from ?¡ã0?¡À to ?¡ã2?¡À which denotes the massive roller.
Sprockets
Normally sprockets must be generated specially for these chains according for the ASME/ANSI B29.3 and B29.four standards on the other hand, for Transmission Series and Conveyor Series with Regular (modest) Rollers, ASME/ANSI B29.1 Normal roller chain sprockets may well be made use of offered the number of teeth is 30 or much more.
